HEEL-COMPRESSING MACHINE.

SPEGIFCATION forming part of Letters Patent No. 543,732, dated July 30, 1895.

Application filed October 30, 1894. Serial No. 527,458. (No model.)

To all whom it may concern/.-

Be it known that we, JOHN J. Hnvs Vand CHARLES W. GLIDDEN, both of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Heel-Oompressing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention has for its object to improve the operative mechanism of heel-compressing machines to therebyincrease their efficiency, our improvements being herein illustrated as applied to the machine represented in United States Patent No. 530,046, granted November 27, 1894.

One part of this present invention relates to improvements in the pusher of the heelfeeding mechanism, whereby it may be adjusted and thereby adapted to act uponl heelblanks of different thickness; also, to improvements in the hopper whereby it may be more readily adapted to heel-blanks of different sizes.4 We have also applied to the machineguards co-operating with the hopper to prevent the accidental escape of heel-blanks therefrom, thus avoiding the falling of ablank into the working machinery.

The particular features in which our invention consists will be hereinafter described, and defined in the claims at the end of this speciiication.

Figure 1 is a vertical section of a sufficient part of the heel-compressing machine referred to, with our limprovements added, to enable our invention to be understood, the line of section for said gure being in the line Fig. 3, the heel-seat die and parts for moving it being, however, omitted. Fig. 1a shows the block elo detached. Fig. 2 is a detail showing the gate to prevent the accidental escape of a heel-blank from the hopper. Fig. 8 is a top or plan View of a part of the machine shown in Fig. l; Fig. 3a, details of the pawlct1T to be described. Fig. 'It is a detail showing part of the sliding cross-head B and removable bottom and wall. Fig. 5 is a section in the irregular dotted line x', Fig. 3. Fig. 6 is a section in the line m2, Fig. 5, looking to the right. Fig. 7 is a detail showing an under side view of the heel-blank support to support the heel t0 be acted upon by the pusher. Fig. 8 shows a modified form of pusher; Fig. 9, a cross-section thereof in the dotted line x3.

The side pieces A, the stationary cross-head A the tie-rods A3, connected thereto and in practice extended down substantially to the bottom of the framework, the movable crosshead B having' an attached vertical post or guide-rod sliding in a bearing in said crosshead A', the girt C, its attached bracket C', bracket G2, pin G', lever G, and rocker-lever H pivoted on said pin, carriers i, edge-compressing dies jconne'cted thereto, the detachable tread-plate 14, the heel-seat die D, having a removable plate d, the breast-gage d', the link 30, the adjustable table E', its depending shank 19`and upright arm 17 are by like letters in said patent, and said parts, and may be all substantially as indicated which are movable, may in practice derive their movement as therein provided for, and need herein no further description except in illustration of our improvements as applied to the old and named parts.

The heelfeeding' mechanism, as herein shown, consists, essentially, of a plate am, an under side view of which is shown in Fig. 7, and which is also shown in section in Figs. 5 and 6. The plate am, designated as the heelblank support, rests in a suitable guideway formed in the table E', and is slotted, as at @12, and provided at its under side with a suitable stop pin or projection als and with a buffer Q14, preferably a piece of rawhide. The buffer 0,14 at the end ot' the plate am will, in practice, meet the edge of the tread-plate 14 as the heel-blank support arrives in its farthest position to the left, viewing Fig. 5, thus stopping said plate, while the pusher (to be described) continues to travel in the same direction, it sliding frictionally along the said plate and pushing the heel-blank-from said plate into position on the tread-plate.

The plate 0.10 is provided at its upper side, at one side of the slot 0.12, with a series of ratchet-teeth am adapted to be engaged by a spring-controlled pawl a, (shown by dotted lines in Fig. 5 and in detail in Figi 3a), 'said pawl being pivoted at als and having .a lug 0,19, which, in the reciprocation of the pusher P, rides over a cam-ledge d20 on the table E', said pawl, for apart of the stroke of the pusher derived from the link 30, common to said patent, away from the heel-compressin g mechanism, engaging said ratchet teeth to thus effect the movement of the support am with it back to its proper starting-point, the said lug striking the high or throw part of said cam-ledge and disengaging said pawl from the said ratchet-teeth in order that the pusher may slide on the support am to uncover its front end, substantially as provided for in said patent.

The pusher P is composed essentially of a bottom plate p10, on which is mounted the pawl a, referred to, and of an adjustable top plate composed, preferably, of two plates, 19121913, one being made longitudinally adjustable on the other by screws p14 on one entering slot of the other plate, as best shown in Figs. 3 and 5. The top plate of the pusher has been by ns made vertically adjustable in order that the thickness of the pusher may be made more or less to better adapt it to act from the seat to the tread ends of heels of dierent height and composed of several lifts, and by making the top plate adjustable as to its length the acting end thereof may be put in proper position to adapt it to the slope of the side or edge of the heel-blank, as some heels areV made more or less tapering externally.

In Figs. 3, 5, and 6 it will be understood that the bottom plate of the pusher has a boss pmx. (Shown as screw-threaded externally and internally.)

The internal threads receive a set-screw p15, surrounded under its head by a Washer p16, having suitable holes or projections to be engaged by a suitable tool and be rotated when released from the said set-screw, the said washer having suitable pins or projections p18, (see Fig. 5,) which enter suitable holes in the threaded bushing p19, having an external flange on which may rest the plate p12, said bushing, as shown, being free to rotate in the latter plate and being threaded to engage the external threads of thc boss pmx.

It will be understood that the rotation of the Washer and bushing referred to, when the set-screw is relaxed, will enable the operator to increase or decrease the effective thickness of the pusher.

Believing ourselves to be the first to make a pusher adjustable as to its thickness, this invention is not limited to the employment only of the adjusting devices shown in Fig. 5, and instead we may employ any other suitable or equivalentmeans to effect the result stated.v

One such modification is shown in Figs. 8 and 9, wherein pmx shows the bottom plate of the pusher and p12* a part of the top plate, suitable adjusting-screws p2", having each a Iianged head, being screwed into the bottom top plate, a setscrew p21 contining the said plate iu adjusted position, The bottom plate p10 of the pusher has a guide-lug p22 to fit and slide in slot L12 and an extended threaded shank p23, which receives on it a suitable friction-block p24, one or more nuts p2 being screwed onto said threaded shank to cause the friction-block to be pressed with greater 'or less force against the supporting-plate am to prevent any accidental slipping of the pusher with relation to the plate am, for the purpose fully set forth in said patent. As the pusher is moved positively to the left, viewing Fig. 5, which is toward 'the heel-compressing mechanism, the pusher, with its acting end against the heel-blank lying on the support 0.10, will both be moved together frictionally until the heel-blank is in position to be discharged from the support am, and the bui-fer a referred to, having met the treadplate, or the pins (113 having met a fixed part, preferably of the table E', the further movement of said support is arrested while the pusher continues its movement 'in the same direction sufiiciently far to push the heelblank from the support 0.10 upon the tread plat-e and between it and the heel-seat dic then elevated sufficiently for that purpose. The pusher, it will be remembered, takes the lowermost heel-blanks, one after another, from a pile of blanks in the hopper C10 and takes them to the tread-plate of the heel-blank carrier, said tread-plate being carried by the lever G referred to, which in practice is and may be operated in time and order as provided for in said patent.

In the modified form of pusher, Fig. 8, one member p13* of the top plate is shown as pivotally mounted at p30 on the plate p12", to thus enable it to tip and adapt itself to the shape of the heel.

The hopper herein to be described is composed of several parts, viz: a front wall-plato d10, att-ached to the arm 17 by asuitable screw C112, (see Fig. 3,) a curved plate (Z13 having a slotted shank d14 attached in an adjustable manner by an adjusting bolt or device d14X on a flanged part of the table E', and a curved plate d attached in an 'adjustable manner by ad justing-bolts di to the wall-plate d1.

The two plates dd may be adjusted readily on or with relation to the plate di" to accommodate heel-blanks of the particular size to be used. In this present instance the block elo, (shown separately in Fig. 1%) on which the tread-plate I4 rests, is connected with the lever G bya suitable bolt e, (see Fig. 1,) said block having a shank extended from oneside into a slotin said lever, the said shank being straddled bythe divided or bifurcated shank d' of the heel-seat die-carrier, the inner face of said shank constituting a guide for the breast of the heel-blank.

The heel-seat die D is jointed by a pin 48 with a lever h5 mounted on a link It pivoted in the carrier G, said lever h5 and link being common to said patent, the lever h5, but partially shown, bcingin practice connected tog IIO

with lev'er H, substantially as provided for in said patent and for the 'same purpose. In the patent referred to the block elo was made to seat directly onto the movable crosshead B, preparatory to moving the same vertically to compress a heel. Herein we have provided the said cross-head with a circular opening in which we have laid preferably a circular-platef10, and on this plate have laid a lining-rim f1?, having an opening in which the block el@ may enter as the said block comes v to rest on the platefw.

The removable plate and liningrim may be changed for others in case it is desired to change the block elo and thus insure correct contact of the parts. The lining-rim (shown as circular externally) is prevented from rotating by suitable doWel pins or devices e30, (see Fig. 1,) and said dowel-pins may enter any one of a series of holes or notches in the plate flo, and the latter may be rotated, if desired, to bring a new or unused surface .into position to sustain the block elo.

To prevent the accidental escape of the heel-blank from the hopper we have provided the table E at the delivery side of the lower end of the hopper with a gate g1, pivoted at 912, said gate having a pin or projection Q13 which is connected by a spring Q14 to a pin or stud g15 of the said table.

The gate has a pin or projection gw, which' is normally held against the shank d of the heel-seat die, as shown y in Fig. 3, by said spring, and as the lever G is turned toward the movable cross-head B, with the heelblank between the tread-plate and heel-seat die to be compressed, the said spring g, as the shank d moves into compressing position, acts to lift the inner end of said gate into the position shown by dotted lines, Fig. 2, and thus prevent the escape of a heelblank from the space below plates d10 d; but as soon as the lever G is moved backwardly away from said cross-head the shank d', by acting on said pin gw, turns it into the position shown by full lines, Fig. 2, leaving the track or passage open for the pusher to push a heel-blank out of the hopper.

. A lug gfon the gate g1D acts against a suit vable stop Q20, (shown by dotted lines, Fig. 2,)

and thus stops the gate in closed position.

The table has suitably attached to it, as by screws h2o, the shank of a rod 7121, which sustains a delivery-chute hw, the upper end of which is located opposite the tread-plate 14, when the lever G is in its outwardor retracted position, the chute being inclined toward the delivery end, so that a compressed blank ejected from the tread-plate .by the contact with, it may be, of an incoming heel-blank, may be directed to a suitable box or receptacle. (Not shown.)

To prevent the accidental escape from the hopper, at that side thereof next the crosshead B, of a blank when the pusher is acting to take a blank therefrom and put it onto the tread-plate 14, we have provided the hopper at its side next the said cross-head with a guard m20.

To prevent a compressed heel, traveling down a chute 71,22 from rising therein and getting over the side walls thereof, we have provided the chute with atop guard m21.

Our improvements relating to the pusher and thesupport for the heelfblank and the hopper may be employed to advantage in any heel-compressing machine.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-
